Ms Hanson said the raid meant several parents who were relying on the products were now left urgently short of supply.

"This has been brought to my attention, now, I have asked the Prime Minster, not in a conversation but in a text to him yesterday to please look at an amnesty for these people so they can still access this medicinal cannabis," Ms Hanson said.

When asked if legalising medicinal cannabis presented difficult questions in terms of Australian criminal laws Ms Hanson said such arguments ignored existing exemptions.

"You tell me what is the difference when we allow shooting-up galleries where we allow people to take hard drugs?" she asked.

"We say here is a clean needle, you can get yourself out of your brain.

"Or we say here take your illegal drugs when in some cases women are destroying the foetus but at the same time we're saying this isn't okay.

"I just hope common sense prevails."

The office of Prime Minister Malcolm Turnbull has been contacted for comment.
